Questions
Frequently asked questions
Is Fairwood tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fairwood, PFOS 4.6 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 1.3 µg/L against the 15 µg/L action level. WHITWORTH WATER DISTRICT 2 (PWSID WA5396601) has a Purity Score of 74/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Fairwood?
WHITWORTH WATER DISTRICT 2 (PWS ID WA5396601) is the public water system on record for Fairwood, Washington, serving about 26,883 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Fairwood get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Fairwood's water?
Yes. In EPA's UCMR 5 testing (2023-10-16 to 2024-07-01), PFOS was measured at 4.6 ng/L against a 4 ng/L federal limit. PFBS (5.2 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (3.1 ng/L, below the 400,000 ng/L state limit) were also detected. PFPeA (3.5 ng/L) was also detected; it has no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Fairwood's tap water?
WHITWORTH WATER DISTRICT 2's most recent lead 90th-percentile result (2022–2024) was 1.3 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
What does the latest Fairwood water report show?
PurityMap's current record for Fairwood holds 31 findings: 1 above a reference, 3 detected within the reference, 1 detected with no limit and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
